Navigating the intricate landscape of face oils can often feel like piecing together a challenging puzzle.

As a specialist in skincare formulation focusing on face oils and oil serums, I have devoted extensive time to understanding this complex domain. Today, I am excited to share my nuanced observations regarding certain oils, particularly those I consider to be the least beneficial for facial care and should be excluded from your beauty regimen.

It’s essential to clarify that there is no unequivocally “bad” oil. Each oil possesses a distinctive composition of fatty acids, as well as unique advantages and disadvantages. An oil that works remarkably well for one skin type may not yield the same results for another. Some oils are great for body care or hair care but may not be suitable for use on the face. Additionally, while an oil might be beneficial for you, it may not be universally effective for other users of skincare products.

The appropriateness of an oil for facial use is merely one aspect of my evaluations. The implications of these oils extend beyond the skin surface. Factors such as sourcing practices, environmental impact, and ethical considerations regarding their production add significant depth to this discussion.

Discover the Criteria for Identifying Oils on the bareLUXE Not Recommended List

When you think of face oils, the term “all-natural” often comes to mind, and in many cases, this assumption holds true. However, focusing solely on natural ingredients is just scratching the surface when formulating effective products for your face.

Many of these oils play roles in skincare; in fact, small quantities of some may even be included in our formulations for specific reasons. Nevertheless, these oils do not make our list of preferred choices, and most should generally be avoided for facial application.

In our pursuit of improved skincare, various characteristics can place an oil on the bareLUXE not recommended list:

This article is not intended to vilify specific oils but rather to empower you as an educated consumer. By grasping these complexities, you can make informed skincare choices that not only cater to your skin’s specific needs but also resonate with your ethical principles.

Let’s dive deeper and explore the often-overlooked aspects of these oils.

Exploring the 18 Face Oils to Avoid and Their Issues

Wheat Germ Oil: A Common Skincare Pitfall

Primary Concern: High Comedogenic Rating

Wheat germ oil, extracted from the germ of the wheat kernel, is rich in vital nutrients like vitamins and minerals. However, its application in facial skincare has raised eyebrows due to its high comedogenic rating, indicating a strong likelihood of clogging pores and potentially triggering acne outbreaks.

The term comedogenic refers to an oil’s propensity to block pores, leading to blackheads or pimples. The comedogenic scale ranges from 0 (non-comedogenic) to 5 (highly comedogenic), with Wheat Germ Oil unfortunately scoring a 5!

Although wheat germ oil contains a substantial amount of oleic acid (approximately 25%), this alone doesn’t account for its pore-clogging tendencies. Its richness in diglycerides—where two fatty acid chains are attached to a glycerol molecule—makes it more polar and more likely to interact with skin lipids in a way that clogs pores. Additionally, the viscosity of this oil, partly due to its high vitamin E content, contributes to its inability to absorb easily into the skin.

As a result, wheat germ oil tends to leave an occlusive layer on the skin, further increasing the risk of pore blockage—making it particularly unsuitable for those prone to acne.

Coconut Oil: A Double-Edged Sword

Primary Concern: High Comedogenic Rating

Coconut oil boasts a comedogenic rating of 4, indicating a high likelihood of pore blockage, which can lead to acne flare-ups. The primary factor behind this is its significant concentration of lauric acid, which constitutes about 50% of the oil’s fatty acid profile.

As a saturated fat, coconut oil is solid at room temperature, possessing a dense, heavy texture that tends to remain on the skin’s surface. This can trap sebum and dead skin cells beneath, raising the risk of pore clogging and subsequent acne.

Despite its popularity in DIY skincare for its hydration and antimicrobial properties, the potential for pore clogging suggests that coconut oil is best kept away from the face, especially for individuals with oily, acne-prone, or sensitive skin types.

Marula Oil: Benefits vs. Drawbacks

Primary Concern: High Oleic Acid Content

Extracted from the kernels of the marula tree native to Africa, marula oil is lauded for its wealth of oleic acid, vitamin E, and antioxidants, contributing to its hydrating and protective qualities. However, its high oleic acid concentration can pose challenges for certain skin types.

Oleic acid, a monounsaturated fatty acid, makes up approximately 70-78% of marula oil. While this fatty acid offers excellent moisturizing benefits, its thicker, denser nature can become problematic, particularly for those with acne-prone or oily skin. The oil tends to rest on the skin’s surface, potentially trapping sebum and dead skin cells, thereby leading to clogged pores and breakouts.

For individuals with such skin types, exploring alternatives with lower oleic acid content and higher proportions of linoleic acid may prove to be more beneficial.

Soybean Oil: Hidden Concerns

Primary Concerns: Comedogenicity, Sustainability, Allergens

Similar to wheat germ oil, soybean oil possesses unique traits that heighten its potential to clog pores, even if its fatty acid composition doesn’t initially suggest a high comedogenic rating.

Soybean oil is particularly notable for its high content of phytosterols, such as beta-sitosterol and stigmasterol. While these compounds are linked to potential anti-inflammatory and cholesterol-lowering effects when ingested, they may disrupt the skin’s lipid barrier when applied topically and could contribute to pore clogging by affecting sebum production and pore function.

Additionally, soybean oil is a well-known allergen; soy allergies rank among the most prevalent food allergies globally. For individuals sensitive to soy, topical use can result in inflammation and irritation, further increasing the likelihood of pore blockage.

Finally, it’s crucial to address the sustainability and humanitarian implications associated with soybean oil. The cultivation of soybeans significantly contributes to deforestation, particularly in the Amazon rainforest, and often involves extensive pesticide and fertilizer use, which can lead to pollution and ecological damage. Furthermore, soybean farming can cause land rights conflicts, particularly in developing nations, where large areas are utilized for monoculture, leading to biodiversity loss and displacement of local communities.

Corn Oil: A Mixed Bag

Primary Concerns: Comedogenicity, Environmental Impact

Derived from the germ of corn kernels, corn oil has a more balanced fatty acid profile, earning a moderate comedogenic rating of 3. We typically steer clear of any oils rated higher than 2 for facial use.

However, the sustainability aspect of corn oil is much more pressing. Environmentally, corn farming often entails intensive agricultural practices and significant pesticide application, contributing to soil degradation and raising sustainability concerns.

Cottonseed Oil: A Cautionary Choice

Primary Concerns: Comedogenicity, Environmental Sustainability

Cottonseed oil presents several issues that warrant its placement on our bareLUXE not recommended list. Though it’s less commonly included in skincare formulations than other oils, it poses significant concerns, particularly for facial use.

In addition to the potential for clogging pores, cottonseed oil raises environmental red flags. It is categorized as a heavily treated crop, requiring extensive pesticide and synthetic fertilizer use during its cultivation. These practices lead to soil degradation, water pollution, and detrimental effects on local biodiversity.

Moreover, the extraction of oil from cottonseeds typically involves energy-intensive processes and chemical solvents, contributing to further environmental pollution. Collectively, these factors render cottonseed oil undesirable in the context of holistic skincare.

Flax Oil (Linseed Oil): Not Ideal for Facial Use

Primary Concern: Comedogenicity

Flax or linseed oil, extracted from flax seeds, is celebrated for its high content of omega-3 fatty acids and noted for its anti-inflammatory properties, primarily through dietary intake. However, when exposed to light and heat, alpha-linolenic acid in flaxseed oil can oxidize quickly, potentially leading to skin irritation. Furthermore, its thick consistency may clog pores, especially for individuals with oily or acne-prone skin.

It’s best to reserve this oil for culinary uses rather than applying it to your face!

Palm Oil: A Controversial Ingredient

Primary Concerns: Comedogenicity, Ethical Issues, Environmental Impact

Palm oil is derived from the fruit of the oil palm tree and is rich in vitamins A and E, along with possessing emollient properties. However, its high composition of palmitic acid (44%) renders it highly comedogenic, making its use on the face a potential trigger for acne breakouts.

Numerous skincare formulations include derivatives of palm oil, yet the production of palm oil is a leading cause of deforestation in regions such as Indonesia and Malaysia, raising significant environmental concerns including biodiversity loss and increased carbon emissions.

Additionally, the palm oil industry has faced serious scrutiny for poor labor conditions and violations of workers’ rights, highlighting humanitarian issues that warrant consideration.

While initiatives to improve sustainability and labor conditions are in progress, the pervasive nature of palm oil derivatives makes it crucial to stay informed about ethical sourcing and supply chain transparency.

Olive Oil: Benefits and Risks for Facial Skincare

Primary Concerns: Comedogenicity, Sustainability, Potential Inflammatory Effects

Olive oil, globally recognized for its health benefits in diets, may come as a surprise when it appears on a list of less-desirable facial oils. However, a closer examination reveals the underlying reasons.

The fatty acid composition of olive oil includes:

Research regarding olive oil’s potential for inflammation is not entirely conclusive. Some studies indicate that it possesses anti-inflammatory properties owing to its rich antioxidant profile, including vitamin E and polyphenols. Conversely, other studies suggest that olive oil may disrupt the skin’s barrier function, leading to dryness and potential irritation over time. Such disruption could inadvertently heighten inflammation, particularly for sensitive or already inflamed skin.

In terms of sustainability, olive oil production presents both advantages and challenges. On the positive side, olive trees are resilient, able to grow in poor soil conditions and harsh climates. They produce fruit for many decades, aiding in biodiversity and soil conservation.

However, olive farming can be water-intensive, particularly in water-scarce regions of the Mediterranean. While traditional dry-farming methods can alleviate some concerns, irrigation is increasingly used to enhance yields, putting a strain on local water resources.

Another significant issue is the waste generated during olive oil extraction. Olive mill wastewater contains a high concentration of organic compounds, making sustainable disposal challenging. If not treated correctly, this can lead to water contamination, although initiatives to convert this waste into bioenergy or fertilizers are gaining momentum.

Lastly, the demand for high-quality extra virgin olive oil has led to instances of fraud and mislabeling, misleading consumers and potentially driving unsustainable practices among producers.

Emu Oil: Ethical Considerations

Primary Concern: Animal Cruelty

Emu oil is derived from the fat of the emu bird and has been praised for its anti-inflammatory and skin-softening properties. However, as an animal-derived product, it raises significant ethical concerns.

The process of extracting emu oil involves the slaughter of emus, which raises serious animal rights issues. Those committed to vegan or cruelty-free skincare will likely prefer plant-derived oils that can provide similar benefits without the ethical dilemmas.

Mink Oil: Ethical and Skin Concerns

Primary Concern: Animal Cruelty

Mink oil is obtained from the fat of minks and is rich in palmitoleic acid, an omega-7 fatty acid known for its moisturizing properties. However, the production of mink oil raises significant ethical concerns due to its reliance on mink farming, which is widely condemned for inhumane practices.

Moreover, mink oil has the potential to clog pores, leading to breakouts, especially for those with acne-prone skin. Considering both the ethical dilemmas and the risk of skin issues, mink oil is generally not recommended for facial skincare.

Lanolin: Weighing the Pros and Cons

Primary Concerns: Allergens, Animal Cruelty

Lanolin, a waxy substance secreted by the sebaceous glands of sheep, is commonly used in skincare for its emollient properties. However, it is notorious for being a common allergen, potentially causing skin irritation and contact dermatitis in sensitive individuals.

Additionally, as an animal-derived ingredient, lanolin may not align with the values of those who practice vegan or cruelty-free skincare. Therefore, individuals should use lanolin with caution, particularly if they have sensitive or allergy-prone skin.

Tallow: An Unfavorable Choice

Primary Concerns: Comedogenicity, Animal Cruelty

Tallow is a type of rendered fat traditionally sourced from beef or mutton. It has been used in skincare for centuries due to its skin-compatible composition. However, tallow’s high saturated fat content can easily clog pores, making it unsuitable for those with oily or acne-prone skin.

Beyond the concerns related to pore clogging, the use of tallow raises ethical questions, particularly for consumers who prefer cruelty-free or vegan skincare. As an animal product, the use of tallow necessitates the slaughter of animals, posing moral dilemmas for many.

Shark Squalane: Ethical and Environmental Concerns

Primary Concern: Animal Cruelty

Squalane is a hydrogenated form of squalene, a compound naturally found in our skin that plays an essential role in hydration and barrier function. Traditionally, squalane was sourced from the livers of sharks, particularly deep-sea species. While shark-derived squalane is compatible with our skin due to its biomimetic nature, the extraction process leads to significant ethical and sustainability concerns.

The killing of sharks for squalane contributes to the endangerment of various shark species and disrupts marine ecosystems. In light of these concerns, many cosmetic brands have begun to utilize plant-derived squalane, such as that derived from sugarcane.
